Description
GE Multilin F35-E00-VF-HF-8F-H6T-M6T-PXX Universal Relay
The GE Multilin F35-E00-VF-HF-8F-H6T-M6T-PXX, also cataloged as the F35 Universal Relay, operates as a dedicated hardware component for feeder protection, control, and metering within GE Multilin Universal Relay (UR) platforms. The relay executes electrical measurement, protection logic, digital I/O processing, and communication functions for multiple feeder applications.
Profinet / EtherNet Deterministic Network and Firmware Compatibility
The GE Multilin F35 uses the Universal Relay platform communication architecture for deterministic substation data exchange. The CPU and communication module support Ethernet-based protocols including IEC 61850 and Modbus TCP/IP for protection event reporting, control commands, and monitoring data transfer. Firmware flash compatibility is managed through the UR platform software environment, allowing supported application packages and communication configurations to be maintained according to the relay hardware revision.
The relay integrates configurable FlexLogic(TM) processing for custom interlocks, protection schemes, and control sequences. The modular design supports I/O density scaling through CT/VT and digital expansion modules including the H6T and M6T configurations.
Frequently Asked Questions
Q: Does the F35 support hot-swappable module replacement during operation? A: The F35 modular architecture supports field service access to configurable hardware assemblies; however, module replacement procedures must follow GE Multilin maintenance instructions and required system isolation practices.
Q: What communication protocols are available through the CPU and communication module? A: The relay supports IEC 61850 Ed. 1/Ed. 2, Modbus TCP/IP, DNP 3.0 over TCP/IP, SNTP, and RS485-based Modbus RTU/DNP 3.0 communication.
Q: What is the input capability of the 8F CT/VT module? A: The 8F module provides dual-rated 1 A / 5 A current transformer inputs and voltage transformer inputs rated for 60-300 V AC phase-to-neutral measurements.
Field Installation Guidelines
Install the relay in a protected control panel environment with adequate clearance for terminal wiring and front-panel access.
Use shielded communication cables for serial and Ethernet connections where required by the installation environment.
Connect cable shields according to site grounding practices to reduce electromagnetic interference on measurement and communication circuits.
Separate CT, VT, digital input, and communication wiring routes to reduce electrical coupling between signal groups.
Verify CT polarity, VT phase assignment, and terminal identification before energizing protection circuits.
Confirm auxiliary supply voltage compatibility before connecting the HF power supply module.
Ensure protective grounding connections are completed according to substation electrical standards.
Configure protection settings, FlexLogic sequences, and communication parameters after hardware installation verification.
